My favorite part of the translation is this: "He is initially skeptical, but because he is adventurous, he joins a group of Thorin Oakenshield and becomes the "master thief", they need to bring back a ferocious dragon to outwit and the stolen treasure of the dwarves."

Change of plan, they are not going to kill or chase Smaug away, but going to bring the dragon back with them! How's that for a spoiler! They must have found out the going rate of live dragons on the black market was greater than all the gold in the mountain.
